SPECIFICATION forming part of Letters Patent No. 622,104, dated March 28, 1899.

Application filed October 6, 1897. Renewed January 12, 1899 Serial No.702,005. (No model.)

To all whont it may concern:

Be it known that I, SIMEON BERARD, a citizen of the United States, and aresident of Fall River,in the county of Bristol and State ofl\Iassachusetts,have invented certain new and useful Improvements inSpinning-Frames;

andI do hereby declare that the following is a mechanism forautomatically stopping the machine when the bobbins are full.

The invention consists in the novel construction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawings,- Figure 1 is a side elevation of aspinning-frame constructed in accordance with my invention. Fig. 2 is afront elevation of the same; Fig.' 3 is a plan view, on an enlargedscale, of the cam-frame, showing the filling and building andstop-motion cams and other parts. Fig. 4 is a detail perspective view ofthe building and stop-motion cam. Fig. 5 is a similar view of thefilling-cam. Fig. 6 is a side view of the slide and feed-cam.

In the said drawings the reference-numeral 1 designates themachine-frame, and 2 the vertically-movable ring-rail, supported by a'rod 3, passing through a hole in the horizontal spindle-rail 4. Thelower end of this rod is pivotally connected with a lever, hereinafterdescribed, for vertically reciprocating the ring-rail.

The numeral 5 designates the spindles, jour naled to the rail 4 andprovided with whirls 6, by which they are rotated.

The numeral 7 designates the bobbins on said spindles.

The numeral 8 designates the cam-frame near the bottom of the machine atone end, provided with a horizontal shaft '9, provided at one end with aworm-wheel 10, with which meshes a worm-gear 12, journaled to themachine-frame and provided with a sprocketwheel13. Passing around thissprocket-wheel is a sprocket chain 14, which also passes around asimilar sprocket-wheel15 at the up per end of the machine, the shaft ofwhich is provided with a cog-wheel 16, driven by a driving-shaft 17through the medium of pinion 18 and intermediate gears 19 and 20.

Mounted on said shaft are a fast pulley 21 and a loose pulley 23.

The numeral 24 designates a laterally-m ovable shifting device forshifting the belt (not shown) from one pulley to the other.

The shaft 9 is formed with a longitudinal groove 25, with which engagesa screw 26 of a cam 27, loosely mounted on said shaft, so as to slidelaterally thereon, but rotatable therewith by means of said screw. Thiscam I term the filling-cam, as by its action the ring-rail is verticallyreciprocated to insure the even winding of the yarn. Engaging with thiscam is a pin or dog 28, secured to a slide 29, working in a longitudinalslot 30 on the cam-frame and provided with an inclined feed-cam 31. hiscam has a depending slide 32, formed with a slot 34, through whichpasses a set-screw'35, provided with a washer 36-. By loosening thisscrew the said cam can be adjusted. Connected with the said slide is arope 37 ,which passes around a pulley 38 at one end of the cam-frame andis secured to the segment-head 39 of a lever 40, the other end of whichlever is connected with the rod 3.

. Loosely mounted on the shaft 9 is a building and stop-motion cam 41,the cam-face being in the form of a spiral and having a straightlongitudinal edge 42, as seen in Fig. 4. This cam engages with a pin 43,having a triangular head 43 secured to one of the sides of thecam-frame. Secured tosaid stop-cam is a ratchet 45, with which engages apawl 46, pivoted to a lever 47, journaled on said shaft 9 and providedwith a cam-block 48, which works on the feed-cam.

The numeral 49 designates a stop-motion lever pivoted to a lug 49,secured to the frame 1, the upper end of which engages with a catch 50on .a horizontal rod 51. The lower end of this rod 49 lies in the pathof the cam 41, so that as the latter moves back, as hereinafterdescribed, it will strike and actuate the same.

Connected with this catch is a chain 52, having a weight at its lowerend which shoots the rod outward when the lever releases the catch,striking the belt-shifter and shifting the belt from the fast to theloose pulley and stopping the machine.

At the beginning of the operation thebnilding and filling cams will beat the left of the frame 8, with the pin 43 engaging with the front enda of the spiral face of cam 41. The machine is now set in motion byactuating the lever 47 by hand, so that the pawl will turn ratchetwheel4:5 sufficient to allow the lower end of rod 49 to clear the endb of cam41. The belt is then shifted from the loose to the fast pulley, when theupper end of rod 49 will engage with catch 50, so as to hold the rodwhich actuates the belt-shifter. The shaft 9 will now be rotated throughthe medium of the worm and worm-wheeland connections with the drivingshaft. As said shaft rotates, the filling-cam is correspondinglyrotated, which, acting on the dog of the slide, will cause the latter tobe reciprocat'ed back and forth. The said slide makes one reciprocationfor each revolution of and be in g pushed by the cam toward theworm-wheel during one half of its revolution, and consequently elevatingthe ring-rail through the rope, lever, and rod, and during the otherhalf of the revolution allowing the slide to be pulled in the oppositedirection by the weight of the ring-rail. This reciprocation of theslide is caused by the peculiar formation of the cam. As said slide ispushed forward, as described, the cam on the feed-lever will drop orfall as the feed-cam travels from beneath the same, the pawl thereoftraveling over the teeth of the ratchet-wheel; but on the backwardmovement of the slide the feed-cam will elevate the said lever, and thepawl engaging with one of the teeth of the ratchet will turn the same adistance equal to one or more teeth, according to the adjustment of thefeed-cam. The building and stop cam will be correspondin glyrotated, and the spiral face engaging with the fixed pin 43 will cause the said camand the filling-cam to be moved forward. This operation will be repeateduntil the bobbins are full, when the building and stop cam will havemade a complete revolution. The said cam will new ride off the pin, whenthe building and stop and filling cams and slide will be returned tonormal position by the weight of the ring-rail acting through the mediumof the rod connected therewith, the lever, and the chain connected withthe slide. As the building and stop cam reaches the end of its backwardstroke its end will strike and operate the stop-lever, releasing it fromthe catch of the horizontallymovable rod, which will be projectedoutwardly to operate the belt-shifter.

From the above it will be seen that the filling-cam makes a revolutionwith every revolution of the shaft 9, while the building and stop-motion only completes its revolution when the bobbins are full, themovement of the filling-cam being continuous, while that of the buildingand stop-motion cam is intermittent.

Having thus fully described my invention, what I claim is 1. In aspinning-frame, the combination with the vertically-reciprocatingring-rail, the supporting-rod and lever connected therewith, of theslotted cam-frame, the slide workin g therein, the rope connected withsaid slide and lever, the pulley over which said rope passes, the pin ordog secured to said slide, the rotatable shaft journaled in said frameand formed with a longitudinal groove, the filling-cam with which thepin on said slide is adapted to engage, the pin passing through said camand engaging with the groove in the shaft, the worm-wheel secured tosaid shaft and the connections for driving said wheel, substantially asdescribed.
